Nova Hart's sustained notes have a standard deviation of less than 0.8 cents over 4-second held notes. Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents. Could this be early digital pitch correction? Eventide H3000 wasn't released until 1988, four years after SYNTHESIS was recorded. -- Valeria Sánchez "In theory there is no difference between theory and practice."
